DEVICE FOR REMOVING "WATER FROM CREAM.

Application filed July 3, 1924. Serial No. 724,047.

To all whom it may concern:

Be it known that I, Dnmnon A. llharznru,

citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Devices for Removing ater from Cream; and I do hereby declare the following to be a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a device for removing water from the bottom of a cream 5 can.

It is now the common practice for farmers or other cream producers to separate the cream and then transport the same to the creamery or the station. For various reasons there is always a certain amount of water in the cream, and after the cream has been in the can a short time, this water settles to the bottom of the can. It is an unnecessary loss of money to transport the can to the creamery or churning station and othor places with this water therein, which Water is of nouse and simply adds to the transportation charge. It is desirable, therefore, to remove this water from the cream as soon as the same has settled to the bottom of the can.

'It is an object of this invention to provide an extremelysimple and efiicient device for so removing such water.

Itis another object of the invention to provide such a device comprising a long stem on barrel adapted to have its end held closed and'be projected down through the cream in the can to the water in the bottom thereof, through which stem or barrel the water is then pumped.

It is more specifically an object of the in vention to provide such a device having a long barrel as above set forth with a pump at the top of said. barrel, a check valve being disposed at the lower end of the barrel with means for holding it in closed position and a valve equipped discharge spout being exposed at the top of the barrel.

These and other objects and advantages of the invention will be fully set forth in the following description made in connection with the aecom anying drawings, in which like reference (3 aracters refer to the same parts throughout the different views, and in which- Fig. 1 is a view in side elevation of the device showing the same disposed in a can, a portion of the device being broken away and other portions shown in vertical section; and

Fig. 2 is a central vertical section through the lower portion of the device; and

Fig. 3 is a horizontal section taken on line 3 3 of Fig. 2 as indicated by the arrows; Figs. 2 and 3 being shown on an enlarged scale.

Referring to the drawing, a can 1 is shown such as is now commonly used to con vey milk and cream. A body of water 2 is indicated in the bottom of the can, above which is the cream 3. The device or invention comprises an elongated hollow stem or barrel t having lateral openings or notches 4P in its lower end. Adjacent said openings is a valve seat 5, with which a check valve is adapted to cooperate such as a ball 6. The plunger rod 7 is provided having a spider shaped head 8 at its lower end adapted to Contact the ball 6 and hold the same against its seat 5. The cylinder 9 is connected to the upper end of barrel l by threaded connection as illustrated, which cylinder is oflarger diameter than barrel and has a closing cap 10 at its upper end held in place in said cylinder by suitable headed screws passing laterally through cylinder 9 thereto. The plunger rod 7 extends upwardly through the cap stem and at its upper end is provided with a two-armed grip handle 11, said handle being held on the plunger by a nut threaded on the top of rod 7. An

other handle comprising opposite curved arms 12 is secured to the top of cap 10. A plunger 1 is disposed in the cylinder 9, being formed of a circular plate at each side of which is disposed a cup of leather or some other material, and upon each of which is disposed a washer 14". A. short collar or sleeve 16 is secured to the rod '7 below the lower washer 14-" and an elongated sleeve 17 is disposed between the upper washer 14" and the handle 11, said sleeve surrounding the rod 7. At the lower end of'this cylinder and at the upper end of barrel a is a lateral dischar 'e spout 9, which, in the embodiment of tie invention illustrated is shown as part of the casting of cylinder 9. Said spout is pro r is closed.

vided with a valve seat 9" with which a check valve such as a ball 18 cooperates. Said spout 9 is provided with an opening above said ball 18 enclosed by cap 19, which can be removed to give access to said ball.

In operation the plunger 7 williloe moved to the bottom of barrel l with the head contacting ball 6 and holding the same against the seat so that the lower end of the barrel The handle 11 will then be grasped together with the handle 12', and the plunger rod 7 held down against the ball 6. The barrel 4 is then pushed straight downward in the can through the cream sothat the bottom thereof reaches the water 2 in the bottom of the can. The handle 12 is now released and rod 7 and sleeve 17' re iprocated by means of handle 11. Plunger I l is thus reciprocated and pumping action exerted in the cylinder 9 and barrels. litter is thus pumped up and discharged throu 'li the valve 18 and snout 9. The

pumping action is continued until it is H3811 that some milk or cream is being discharged. It. is then ,knownthat substantilly all the water has been removed from the can. Tilt plunger rod. 7 can then again be moved downward to hold the valve 6 closed, and the device removed. Any water which is in the barrel loan thus be lifted out with '4 he device. I c I 7 From the above description is seen that "applicant has provided a very simple. and efiicient device for the purpose intended. It is very desirable to remove the water from the bottom of the can for this has been a 'verydifficult operation when an ordinary closed bottom canhas been used. With upplicants device the operation can easily and quickly be performed. The device is e tremel sim )le easil and me); )ensivel made.

very successful and efficient. V

"It will, of course, be understood that various changes will be made in the form, details, arrangement and proportions of the parts, without departing from the scope of applicants invention, which, generally stated, consists of a device capable of carrying out the objects above set forth, such. as shown and described and defined in the appended claims.
